WATCHCASE.

Specification of Letters Patent.

Patented Jan. 2, 1917.

Application filed July 19, 1916. Serial No. 110,073.

To all whom it may concern:

Be it known that 1, CHARLES L. Daron LIER, a citizen of the United States, and residing in the borough of Brooklyn of the city of New York, county of Kings, in the State of New York, have invented certain new and useful Improvements in \Vatchcases, of which the following is a specification, reference being had to the accompanying drawing, forming a part hereof.

This invention relates to the so-called invisible connections by which a watch adapted to be carried on a chain or as a brooch or chatelaine watch, may also be connected to two ends of a bracelet or other means of carrying a watch on the wrist, such connections, however, not being readily visible when the watch is used on a chain or otherwise. Various forms of disappearingconnections have been devised heretofore, such connections being capable of being extended when required for use and of being concealed within the contour of the watch when not required for use.

The object of the present invention is to provide a different form of invisible connection which shall not require any part to be attached to the case and capable of being extended therefrom.

In accordance with the invention the watch-case is provided with a hole or recess to receive the end of a link of a bracelet or chain or an eye of a metal connecting device for a strap or ribbon, while a pin, carried orheld in place by the watch-case, is provided for engagement with such link or eye, engagement and disengagement between the link or eye and the watch-case being permitted by the opening of some part of the case, such as the front or back or bezel..

The invention will be more fully explained hereinafter with reference to the accompanying drawing in which it is illustrated and in which,-

Figure 1 is a view in front elevation of a watch-case which embodies the invention, the end portions of a strap or wristlet for carrying the watch being also shown. Fig. 2 is a detail view on a larger scale and partly in section, showing details represented in Fig. 1. Fig. 3 is a partial view in section on the plane indicated by the line 33 of Fig. 2. Fig. 4 is a view similar to Fig. 2 but showing a slightly different embodiment of the invention. Fig. 5 is a partial view in section indicated by the line 55 of Fig. 4.

Fig. 6 is a view similar to Figs. 2 and 4 but showing still another embodiment of the invention. Fig. 7 is a view in partial section ndicated by the line 77 of Fig. 6. Fig. 8 1s a. view similar to Figs. 2, 4 and 6 but showing a further embodiment of the invention. Fig. 9 is a view in edge elevation of the construction shown in Fig. 8, with the case open. Figs. 10 and 11 are views showing still another modification.

The watch ais shown in Fig. 1 as provided with the usual winding and setting crown b and how 0 for engagement as usual with a chain or with one end 03 of a bracelet or wristlet. The other end d of the wristlet is shown as having a suitable connecting device 6 for engagement with the wristlet and provided also with an eye e. All of these parts may be constructed substantially as usual.

Some part of the watch-case is provided with a hole or recess to receive the eye 6 so that it may be engaged and held therein by a pin or stud which is covered and concealed from view by some portion of the watch-case, so that when the connecting device 0 is detached from the Watch-case the latter has nothing to suggest the possible use of the watch as a wrist-watch except the orifice which receives the eye of the connecting device and is not visible except when the watch is viewed from the edge.

As shown in Figs. 2 and 3 the recess 7 is formed in one side of the watch-case center a. and is covered by one of the movable parts of the watch-case, indicated at (L which might be the back or the bezel, or the front cover of a hunting-case watch. A pin or stud g is also provided and is adapted to engage the eye or link 6' and retain it in engagement with the watch-case. It is shown in this instance as a pin formed separately from but carried by the movable part a of the watch-case and adapted, after pass ing through the link or eye 6, to enter, for greater security, a hole a in the watch-case center. When the watch-case is opened, as by movement of the movable part a with respect to the center a, the eye or link 6' is introduced into the recess 7. The movable part a is then closed upon the center a. causing the pin 9 to be extended through the eye or link and thereby prevent its withdrawal from the case.

In the construction shown in Figs. 4 and 5 the watch-case center a is provided with a similar recess 7 and the movable part a? of the watch-case is provided with an integral stud g which, when the watch-case is closed, enters the eye of link e and prevents its withdrawal.

I In the construction shown in Figs. 6 and Z the recess is formed as before in one side of the center a and a stud g is formed of an integral part of the center, the free end after engagement of the stud with the link or eye thereof being covered with the movable part a of the watch-case.

In the construction shown in Figs. 8 and 9 the recess 7 is formed wholly between the sides of the watch-case center a and the pin 9 carried by the movable part (L2 of the Watch-case, passes through holes formed in the side walls of the recess and through the eye or link as before, retaining it in engagement with the watch-case.

As shown in Figs. 10 and 11 the movable part of the watch-case which covers the pin or stud need not be one of the component parts of the watch-case, but may be a part of such a component part, such as a segmental plate at, movably attached to the back a. by guide pins a", which permit limited movement of the plate at, and itself carrying the pin 5/ to pass through the recess and retain the eye or link therein.

Various other embodiments of the invenflopies of this tion will readily suggest themselves as the requirements of each particular instance may indicate to be desirable.

I claim as my invention:

1. A Watch-case having relatively movable parts and having a recess in one of said parts to receive an eye or link, and a transverse pin or stud to engage such eye or link and retain it within the recess, the pin or stud being covered by the relatively movable part of the case when closed to prevent disengagement.

2. A watch-case having a center and a relatively movable part and having a recess in the center to receive an eye or link, and a transverse pin or stud to engage such eye or link to retain it within the recess, the pin or stud being covered by the relatively movable part of the case when closed to prevent disengagement.

3. A watch-case having a center and a relatively movable part and having a recess formed in one side of the center to receive an eye or link, and a transverse pin or stud to engage said eye or link and retain it within the recess, the pin or stud being covered by the relatively movable part of the case when closed to prevent disengagement.

This specification signed this 17th day of July, A. D. 1916.
